SELFHEATIN G SAD-IRON.

Specicaton of Letters Patent.

Patented March 3, 1908.

Application filed May 14. 1906. Serial No. 316'820.

To all whom it may concern.

Be it known that l, JOHN E. FRY, a citizen of the United States, residing at Gibsonburg, l the said body portion 1.

1n the county of Sandusky and State of Ohio, have invented a new and useful Self-Heating Sad-Iron, of which the following is a specification.

This invention has relation to self-heating sad-irons and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide a self-heating sad-iron from which the heat is permitted to escape in such a manner as not to come in contact with the hand of the operator. In irons of this character much discomfort is caused by reason of the fact that the heat escapes around the sides of the iron and passes up along the hand of the operator. The present invention avoids this disadvantage for when the iron is moved in one direction, the heat escapes out of the end thereof opposite to that located in the direction in which the iron is moving and when the iron is moved in the opposite direction, the heat escapes from the iron in a similar manner. Thus the hand and arm of the operator is continually moved away from the heat which is escaping from the iron. provided for adjusting the air feed to the hydro-carbon burner of the iron.

In the accompanying drawing z-Figure 1 is a longitudinal sectional view of the selfheating sad-iron. Fig. 2 is a perspective view of the handle portion of the iron, as shown in Fig. 1. Fig.' 3 is a longitudinal sectional view of a modified form of the iron, and Fig. 4 is a perspective view of the forward portion of the iron handle, as shown in FiO'. 3.

The iron consists of the body portion 1 which is provided with the usual combustion chamber 2. Said chamber is closed at its upper edges by means of the removable handle part 3. The said handle part is provided with the usual handle 4 below which is located a hand shield 5. The base of the said handle portion consists of the plates 6 and 7 which are located in planes parallel to each other but spaced apart. In the form of Figs. 1 and 2 the said plates 6 and 7 are not closed along theirl longitudinal edges and the bottom plate 7 is provided with a number of dependlng tubes S which when the handle portion 3 A means is also is in position upon the base 1 of the iron eX- tend down into the combustion chamber 2 of The handle posts 9, 9 are made integral withthe ends of the plates 6 and 7 and each with a vertically disposed funnel shaped aperture 10, the mouth of each aperture facing toward the respective end of the iron at which it is located. The hydro-carbon burner 11 is located within the combustion chamber 2 and is provided at its rear end with the air inlet 12. The valve 13 is mounted upon the rear end of the burner and is adapted to slip over the opening 12 in such manner as to regulate the size of said opening and the quantity of air which may pass therethrough. The needle valve 14 is located at the rear end of the burner and is adapted to regulate the flow of hydro-carbon which passes through the pipe 15 from the tank 16. The tank 16 islocated in an elevated position at the forward end of the iron and the connecting pipe 15 passes along the entire length of the combustion chamber 2 where it is contained. The hydro-carbon is subjected to intense heat and is converted from a liquid to a gaseous state in which condition it is burned at the burner 11.

The circulation of air through the combustion chamber 2 and the removal of the products of combustion from said chamber is accomplished in the following manner: Presuming that the iron is being moved by the hand in a forward direction, cold air passes between the plates 6 and 7 and down through the depending tubes 8 into the lower portion of the combustion chamber 2 while the heat and products of combustion pass out of the funnel shaped aperture 10 facing the rear end of the iron. Thus the hand and arm of the operator move in advance of the heat and products of combustion as the same are liberated from the implement. When the iron is moved in a backward direction, the air is introduced into the combustion chamber in the manner as above described but instead of passing out of the rear aperture, the heat and products of combustion pass out through the aperture 10 nearest the pointed end of the iron. This circulation of air and sweeping out of the combustion chamber 2 is accomplished owing to the face that the heat will endeavor to seek the highest possible level, consequently the flame from the burner 11 will pass up against the under side of the post is provided.
